VEHICLE-SPRING.

Specification of Letters Patent.

Patented Dec. 10, 1907.

Application filed March 1.8. 1907. Serial No. 363,091.

To all whom it may concern: Be. it known 'that I, GUsTAV SGHMITT, a citizen ofthe'United States of America, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Vehicle- S prings, of which the following is a specification. This invention relates to vehicle springs, and one of the principal objects of the same is to provide means for absorbing the vibratory motions of the vehicle when the wheels strike a stone or other obstruction, or when the wheels suddenly run into a rut.

Another object of the invention is to provide a recoil spring to be connected to. the ordinary vehicle s ring to limit the recoil action of the vehicle spring when the vehicle is passing over a rough road. I These and other objects may be attained by means of the construction illustrated in the accompanying drawing, in which: I

Figure 1 is a side elevation of a vehicle spring made in accordance with my invention. Fig. 2 is an inside face view of one of the connectinglinks for the springs. Fig. 3- is a sectional View on the line 33, Fig. 2, looking in the direction of the arrows. Fig. 4 is a detail sectional view showing the ner of mounting the ends of the recoil spring on ball bearings within the links.

Referring to the drawing for a more particular description of my-jnvention, the numeral 1 designates the upper bow spring, and

2 is the reversely bowed recoil spring, said two springs being secured together by means of a central spring leaf rece tacle 3 formed integral with the lower mem er of the-spring 2 and bent upward to inclose the other leaves 't 1e shank of'thebolt 11, and

for automobiles and 0t manof which are oppositely beveled or inclined, as at 10, Fig. 4.. A bolt 11' provided witha head 12 having a plain inner'face 13, is secured to the head 14 of the spring 2 by turning its threaded shank 15 in a socket in the end of said head. As shown in Fig. 3 it will be noted that two of such rollers 9 are utilized, one upon each side of the head 14, and these rollers are adapted to engage the flanges 8 and 'the inner surface of the wall 6, thus materially reducing the friction as the springs move toward each other at their outer ends. .Seated in .the bottom of the links 5 is a rubber cushion 16 vide a buffer for the head 14 at the bottom of the links. Steel balls 17 are disposed at the o posite sides of the rollers and bear upon against the head thereof, and againstfthe inclined surfaces of the rollers.

designed to pro- From the foregoing itwill be obvious that a vehicle spring made in accordance with my articularlydesirable mvention, will be found or high speed vehicles, and will serve to prevent undue vibration of the body portlon of the vehicle in passing overrough and uneven roads. Owing to the ball-bearing rollers 9, the relative movement of the springs will not create unthe springs will work due friction and smoothly under all conditions.

Having thus'described the invention, what I claim 1s:

1. A vehicle spring comprising'oppositely springs, and rollers connected to the ends of t e other spring and 'mounted to move in said links.

2. In a vehicle spring, the combination of a bowed spring having rollers mounted upon the o posite ends thereof, and links 0011- necte' tothe other spring and receiving the rollers... 3.
